2006 Sebring v6 2,7
 

I had a code p0202 injector circuit malfunction cylinder number 2. We replaced the cylinder number 2 fuel injector. No change still misfiring when trying to drive it no acceleration. I suspect the injection driver in the PCM might be bad how do I find out? Any advice? I've only had the car 2 weeks it ran low on gas and then this happened.
